Error when subclassing PlayerEntity and adding new attributes

[Mahi]

My EasyPlayer causes an error when trying to use it:

Code: Select all

[SP] Caught an Exception:

I went through the trace all the way to this part: https://github.com/Source-Python-Dev-Team/Source.Python/blob/master/addons/source-python/packages/source-python/entities/classes.py#L127-L131
But I have very little idea what it does and why it raises the error, any ideas? It used to work before an SP update, not sure which.

The error is raised whenever I try to add an attribute to the instance in the __init__ method:

Syntax: Select all

def __init__(self, index):
    self._effects = defaultdict(list)

I am also using a metaclass which overrides the default __call__ method, but does call it in the overridden method, so I can't see how that would create an issue.

You need to call the super class' __init__ prior to setting a new attribute.

You need to call the super class' __init__ prior to setting a new attribute.

I'm not calling it at all... How could I miss that, thanks!
